👩🏫 Teacher Instructions
In the Classroom
This is a genuinely different skill from the single-digit addition and subtraction on our addition and subtraction worksheet — the focus here is place value, understanding that the same digit means something different depending on its position (the 3 in 300 versus the 3 in 30). Use physical base-ten blocks or a place value chart alongside this sheet where possible; the abstract hundreds/tens/ones concept is much easier to grasp with something concrete to point to first.
👨👩👧 Parent Instructions
At Home
Break numbers apart out loud as you work through this together — "247 is 2 hundreds, 4 tens, and 7 ones" — before asking your child to do the same independently. Real-world three-digit numbers (a book's page count, a house number, a price) are a good source of extra informal practice beyond the worksheet itself.
✅ What Successful Completion Looks Like
Not a Traditional "Answer Key"
Since specific numbers on this sheet vary by print, there's no single number key to share. Instead, check that each number is correctly broken into hundreds, tens, and ones, and that any written numbers correctly reflect a stated value. A common early mistake is writing digits in the wrong place-value position (writing "35" instead of "305," for instance, by dropping the zero) — this is worth pointing out directly rather than just marking it wrong, since it reflects a specific, fixable misunderstanding about place value.
